At the time, the 64 MB version was a lot more interesting since games like Doom3, FarCry and HalfLife2 were not out 2-3 years ago... And 64 MB was plenty. If it meant you could clock that 64MB at 600MHz (like me) then it was a definite plus. The rated speed (ns) for the 128MB version was not so forgiving.

Mild agnosticism —the view that the existence or nonexistence of God or gods is currently unknown but is not necessarily unknowable, therefore one will withhold judgment until/if more evidence is available. A weak agnostic would say "I don't know, but maybe you do."
